What Happened: Voicebox is an advanced AI model that can produce realistic, contextually accurate speech output from given text and has the potential to complete tasks for which it was not explicitly trained. Engadget compared Voicebox to what OpenAI's ChatGPT did for text output and what Dall-E did for image generation.
Zuckerberg made the announcement via his Meta Channel on Instagram, accompanied by a video showing how Voicebox can convert text into speech in various styles, how it can handle background noise much like an audio eraser and how it can even replace spoken words.
Built on a foundation of "non-autoregressive flow-matching model trained to infill speech, given audio context and text," Engadget noted Voicebox's training involved more than 50,000 hours of diverse, unfiltered audio in multiple languages, including English, French, Spanish, German, Polish and Portuguese.
Voicebox leverages its varied training to deliver conversationally fluid speech in various languages. In tests, speech recognition models trained on synthetic speech generated by Voicebox performed nearly as well as models trained on real speech, the report said, showing a 1% degradation in error rate.
Why It Matters: One of Voicebox's defining characteristics is its ability to edit audio clips actively, as it can eliminate noise from speech and replace misspoken words. By identifying a noisy segment in the speech, the user can crop it and instruct the model to regenerate the segment, much like using image-editing software to enhance photos.
Unlike existing TTS generators, Voicebox doesn't require extensive source material to mimic a subject. It's the result of Meta's zero-shot text-to-speech training method known as Flow Matching.
While the potential applications of Voicebox are nearly endless, Meta decided not to release the app or its source code to the public as of now due to potential misuse concerns according to Engadget.
